PM or ping(does that exist here?) if you are stuck

Best to ask in this thread so everyone can see the questions and answer in case others have the same issue.

Should I re-run Winterbreak latest version 1.4.1 if I already successfully jailbroken with 1.3.0? (Scribe 2022). (Especially as the changelog says there are fixes for 12th gen?)

Hi @HackerDude, could you please check this thread? Some winterbreakers had troubles that may be or may not be caused by run_bridge.sh script.

Since the instructions said to put "Update_KUALBooklet_*_install.bin", I assumed I should put both these files on the Kindle.

Here is how I read the instructions: First install "Update_KUALBooklet_18b218e_install."

If there is a problem the "Troubleshooting" says to "Try copying the Update_KUALBooklet_hotfix_*_install.bin file to the root of your Kindle when connected to your PC, and then go to Settings > Update Your Kindle, then resume from step 5.

I just installed the first and everything went well. I didn't install the second. Perhaps it doesn't matter if you install both. I just installed the first.

Good luck.

I also have trouble getting this to work on my

Kindle Paperwhite 11 Gen Signature Edition
with the Firmware Version 5.17.1.0.3 (just like the other people in this thread)

1. Installing WinterBreak works
2. Installing the Hotfix works
3. Installing Installing KUAL/MRPI does not work. If I follow every step and finally have to write ";log mrpi" into the searchbar, the screen goes white for some time, then resumes to the homescreen but then there is no KUAL book/app available. The only thing that I can find is a file called KPPMainAppV2_37XX...malbec_bellatrix-xxxxx-crash..."

It seems that this version and Kindle right now doesn't work with the suggested files?

I used the latest files from the suggested downloads, so

MRPI -> kual-mrinstaller-khf.tar.xz directly from the download button on the guide (2451 KB size from 01.10.2025 20:37)
KOAL (Coplate) -> KUAL-18b218e-20250103.tar

Hi, thank you for the hard work.
One question please, does this jailbreak work on Kindle Oasis 10th generation FW 5.17.1?
Thank you

[mergen3107]

It should work

I was also having trouble jailbreaking my Kindle Paperwhite 6th gen, FW 5.12.2.2. I tried the winterbreak jailbreak and hotfix but then got a constant core dump debug popup.

I did a factory reset and tried again, but now the option for "Update Your Kindle" is greyed out when I put the hotfix in the root folder.

I can install MRPI and Kual, but KoReader won't load.
Thanks for the amazing work with the jailbreak! any help would be appreciated

The WinterBreak was successful & KOReader is running on my Kindles:

Kindle Basic (11. Generation), FW 5.17.1.0.3
Kindle Paperwhite 6 (12. Generation), FW 5.17.0
Kindle Paperwhite 6 Signature Edition (12. Generation), FW 5.17.1.0.4
Kindle Scribe (1. Generation), FW 5.17.2

Thank you all so much for the work to get this possible! Grat, amazing work!

Today my Kindle Colorsoft will arrive. On a YT video I have seen a Colorsoft replacement device comes with a newer firmware than the first devices, FW 5.18.0.1.0.1 on the replacement device, FW 5.18.0.1 on the first device.

Works the WinterBreak for FW 5.18.0.1.0.1?
Could someone who did the JB on a Colorsoft please tell me which FW the Colorsoft had.
I read in this thread @BionicGecko did the JB on a Colorsoft and a new device.lua is needed, which is for download in this thread, which FW has your Colorsoft when you did the JB, could you please tell me. Thank you in advance.

What are the directions for undoing the jailbreak and removing ever add-on?

Yes, my Colorsoft is running FW 5.18.0.1.0.1; WinterBreak works fine on that FW, just make sure you’re using the latest version of both the jailbreak and the hotfix. Enjoy!

After this jailbreak how can I delete the lock screen ads? I'm new here.

Contact Amazon and ask. Sometimes they will do so for free, other times they will ask for payment to do so.

WinterBreak works fine on that FW, my Colorsoft is now with JB and my favorite reading software KOReader also runs on the device
